Help with using Cracks and VD

[Striders]

Ok so Im not really big on how to do all this stuff with VD, but I downloaded the Game Need for speed underground 2 off bearshare and I i created an image for both discs or in my case files with alchol 120%, now I got the key for the game and i installed it but when i load disc one with VD it says put in disc 2, so i load in disc 2 and press retry, and then it says,
"Cannot locate the CD-ROM- Please insert the correct CD-Rom and select restart application." Can anyone help me out with this?
